Elaine T Spaketh Thusly:

Well, I soaked it for 2 weeks with daily water changes. The first
couple of days I got very dark water, then a medium color for the rest
of the two weeks. I Googled for info and most people said Mopani can
leach tannins for months. I'm not worried about it; the fish I have
should actually prefer those conditions. If the water gets too dark for
plants despite the carbon in my Aquaclear, I'll add more carbon by using
an air-driven box filter.
Ahhhh, same method as me, same results.
Same "not worried about it" attitude, too.
Sure we're not related? ;-)
